Can someone please check my code and tell me why i am getting the given error above!
public class Order {
private String itemName;
private int priceInCents;
private String discountCode;
public Order(String itemName, int priceInCents) {
this.itemName = itemName;
this.priceInCents = priceInCents;
}
public String getItemName() {
return itemName;
}
public int getPriceInCents() {
return priceInCents;
}
public String getDiscountCode() {
return discountCode;
}
public void applyDiscountCode(String discountCode) {
this.discountCode = normalizeDiscountCode(discountCode);
}
private String normalizeDiscountCode(String discountCode){
discountCode = discountCode.toUpperCase();
char[] codeLength = discountCode.toCharArray();
for(int i=0; i<codeLength.length; i++){
char letter = discountCode.charAt(i);
if(!Character.isLetter(letter) || letter != '$'){
throw new IllegalArgumentException("Invalid discount code");
}
}
return discountCode;
}
}
public class Example {
public static void main(String[] args) {
// This is here just for example use cases.
Order order = new Order(
"Yoda PEZ Dispenser",
600);
// These are valid. They are letters and the $ character only
order.applyDiscountCode("abc");
order.getDiscountCode(); // ABC
order.applyDiscountCode("$ale");
order.getDiscountCode(); // $ALE
try {
// This will throw an exception because it contains numbers
order.applyDiscountCode("ABC123");
} catch (IllegalArgumentException iae) {
System.out.println(iae.getMessage()); // Prints "Invalid discount code"
}
try {
// This will throw as well, because it contains a symbol.
order.applyDiscountCode("w@w");
}catch (IllegalArgumentException iae) {
System.out.println(iae.getMessage()); // Prints "Invalid discount code"
}
}
}

28,694 Pointsseems okay with:
private String normalizeDiscountCode(String discountCode){
discountCode = discountCode.toUpperCase();
for(char letter: discountCode.toCharArray()){
if(!Character.isLetter(letter) && letter != '$'){//DIFFERENT CONDITION
throw new IllegalArgumentException("Invalid discount code");
}
}
return discountCode;
}
if being a Letter is A and being a $ is B, then the positive condition is A || B. To flip that, you get !A && !B.

12,240 PointsOn changing the || to && i am getting the following error :- Hmmm...I ran order.applyDiscountCode("h1!") and I expected it to throw an IllegalArgumentException, but it didn't

28,694 PointsI think you may still be catching the error. You may need to restart the challenge to get rid of unnecessary modifications. I was definitely able to pass using your Order class, but with the above rewritten method.

private String normalizeDiscountCode(String discountCode){
for(char letter: discountCode.toCharArray()){
if(!Character.isLetter(letter) && letter != '$'){
throw new IllegalArgumentException("Invalid discount code");
}
}
return discountCode.toUpperCase();
}
public void applyDiscountCode(String discountCode) {
this.discountCode = normalizeDiscountCode(discountCode);
}
